This invention relates to air or gas compressors, more particularly ofthe portable type. The object is to provide means for securing a moreeffective cooling of the air prior to its passage to the tools operatedthereby.

The preferred embodiment of the invention is illustrated in theaccompanying drawings, wherein:

In the embodiment disclosed a wheeled support or frame 4 is employed onwhich is a housing or casing 5 containing the usualaircompressingmechanism. Thecompressor is shown at 6 and may be of anywell known character. The frame at extends at one end beyond the casing5 and supports a reservoir or container 7 for the air compressed by thecompressor 6. A suitable pipe 8 therefore connects the compressor 6 andreservoir 7 On the compressor reservoir 7, which is ordinarily atransversely arranged tank, is located a suitable support 9 whichcarries the gasoline tank 10 that supplies motive fluid to the engine ofthe compressor. This support 9 is extended and provided with a seat fora combined cooler and manifold. As shown particularly in Figures 2 and 3the cooler or manifold is of tubular form with cylindrical side wallsthat are corrugated as shown at 11. A connection 12 at one end is incommunication with one end of the reser voir 7 and thus air is suppliedto the manifold. Said manifold is furthermore provided with a pluralityof outlet nipples 13 that are internally threaded or otherwise formed topermit the attachment thereto of hose lines leading to the tools to beoperated With this construction the air in the reservoir 7 even thoughit has been pro-cooled, is further cooled when it is transmitted fromthe reservoir to the tools inasmuch as it must Figure 3 1s a crosssectional 3-3 of Figpassthrough the manifold, the corrugations of whichconstitute means for radiating the heat of the air passing therethrough.

WhatI'claim, is: I -'1. The? combination with a supporting frame, of acompressor fmounted thereon, a reservoir for the compressed air mountedtransversely on one end of the frame, a manifold body of tubular formmounted on the reservoir and having heat-radiating means, said bodyhaving communication with the reservoir, and means for attaching aplurality of hose lines to the body.

2. The combination with a support, of a compressor and a reservoir forthe compressed air mounted on the support, means i for supplying thecompressed air in a reservow to a tool, said means including an aircooled manifold through which the air passes to the tool, said manifoldbeing mounted on the support and having connections with the reservoirto receive air therefrom, and said manifold having means for connectinga plurality of tool supply conduits thereto.

3. The combination with a support, of a compressor and a reservoir forthe compressed air mounted on the support, means for supplying thecompressed air in the reservoir to a tool, said means including an aircooled manifold through which the air passes to the tool, said manifoldbeing mounted on the support and having connections with the reservoirto receive air therefrom, said manifold having heat dissipating means,and said manifold having means for connecting a plurality of tool supplyconduits thereto.

4. The combination with a support, of a compressor and a reservoir forthe compressed air mounted on the support, means for supplying thecompressed air in the reservoir to a tool, said means including an aircooled manifold through which the air passes to the tool, said manifoldbeing mounted on supports resting upon said reservoir and havingconnections with the latter to receive air therefrom, and said manifoldhaving-means for connecting a plurality of tool supply conduits thereto.

5. The combination with a support, of a compressor and a reservoir forthe commounted on the support,means forsupplying air from the receiverto a tool, said means including an air cooled manifold mountedhorizontally upon the receiver, and [said manifolddiavingimeans forconnecting there'- to a supply conduit leading lto-iatool.

In testimony whereof I ,rafiix my signature.
